A dymanic chart can be created by refreshing the data provided to the ChartControl. Please see the knowledge base article linked to below for an example:

Please let us know if you would like us to change anything or incorporate any additional support for dynamic charts.

Hi,
The current version does not support custom start positions for the grid lines (this feature is necessary to produce the scrolling effect).
I have submitted a feature request to the development team and I will get back to you once we have more information.
Thank you for your patience.
Regards,
Davis
